Can Dogs Drink Pepsi?

Many people cannot have a meal without drinking coke these days. Even it is refreshing, it is quite harmful in the long-run due to its acidity and contained additives. Yet, it is still a favorite drink for many. Now, some pet parents might be asking, can dogs drink Pepsi?

If you are looking for a direct answer, “No”. Dogs cannot drink Pepsi. In fact, drinking coke may be very dangerous for dogs. Coke and sodas usually contain numerous additives and preservatives that may be a severe threat to your dog’s health.

These ingredients may be suitable for humans to consume in small amounts. However, for dogs, even small amounts of them can lead to many illnesses or even death. We will try to explain why dogs should not drink Pepsi and what you have to do if your dog drank Pepsi, in detail.

Why Can’t Dogs Drink Pepsi?

We have decided that dogs should not drink Pepsi. To make it more understandable to you, it would be best to explain all the possible dangers. Pepsi contains high amounts of caffeine and sugar, which is the main reason why it is so dangerous for dogs to consume. Let’s look at these ingredients in-depth to see their impacts on dogs.


Humans love caffeine. They drink coffee to wake up, to concentrate on their work, or to stay up late while cramming for the upcoming finals. The thing that makes coffee so effective is caffeine. It is basically a stimulant.

While humans may consume it to some degree without a problem, dogs are susceptible to caffeine. You can drink up to a few cups of coffee until your heart rate increase, and you become hyperactive. Your dog, however, experiences much more than this even with a small amount of caffeine.

Caffeine consumption increases the heart rates in dogs as in humans. One of its immediate impacts is hyperactivity. Dogs may become extremely restless and start to shake. Also, they tend to bark a lot.

Caffeine increases the blood pressure in dogs, besides the heart rate. Increased blood pressure may lead to cardiac arrhythmia, which is a serious condition.

Consumption of caffeine in high amounts may cause your dog to have seizures. Your pup may become feverish. Unless it is treated immediately in case of excessive consumption, your dog may get into a coma, which may result in death.


Dogs can get sugar from carbohydrates and fruits that are safe for them to consume. However, the sugar contained in sweets is quite harmful to dogs. Consuming too much sugar can cause cavities. If consumption persists, it can cause weight gain and eventually, diabetes. All these health issues may lead to serious illnesses such as arthritis and heart disease as well.

Soon after consuming sugar, your dog may get an upset stomach. This may result in vomiting as well as diarrhea.

Sugar consumption makes the level of blood sugar suddenly raise and lower. So dogs become hyperactive after having sugar, and not long after, they become depressed. High blood sugar may also cause your dog to become agitated or anxious.

What About Diet Pepsi?

If you think that a diet coke doesn’t contain sugar and, therefore, it may not be harmful to dogs , you are wrong. Many sugar-free products contain xylitol, which is a kind of sweetener. Although it is usually safe for humans when consumed in moderation, even a small amount of xylitol is toxic to dogs.

Xylitol, which causes hypoglycemia by rapidly lowering blood sugar level, is hazardous for dogs. It may cause liver failure in some cases. If not treated immediately, xylitol poisoning can even be lethal for dogs.

It is best to get professional help immediately as your dog’s condition may get worse and result in death.

Primarily, you should keep the products that contain caffeine, sugar, and xylitol where your dog cannot reach. If you have kids, you should teach them not to share their foods with your pup to avoid possible accidents. You can also teach your pup not to beg for the foods you are having.
